# this blacklist of DCC clients is used by the public DCC servers. The
# public DCC servers should only be used by small sites that qualify
# for the free license on the DCC source.
# See http://www.dcc-servers.net/dcc/ concerning DCC
#
# This list contains IP addresses and blocks of addresses of DCC clients
# that persistently cause problems such as sending more than 100,000
# requests per day to the public DCC servers. This list causes the public
# DCC servers to ignore requests even before checking the automatic
# rate-limiting mechanisms.
#
# This blacklist has no direct effect on email.
